Schwarzenegger to Shriver: Put down the cell phone

Gov. Arnold Schwarzenegger is calling out his wife, Maria Shriver, for apparently violating a state law he signed – holding her cell phone while driving.

The celebrity Web site TMZ.com posted two photographs showing Shriver holding a phone to her ear while she's behind the wheel. It says one was snapped Sunday and the other in July.

On his Twitter feed Tuesday, Schwarzenegger wrote to TMZ.com founder Harvey Levin: "Thanks for bringing her violations to my attention. There's going to be swift action."

Schwarzenegger spokesman Aaron McLear said that by swift action, the governor means he'll ask his wife not to hold the phone while driving. A law that took effect in 2008 requires California drivers to use a hands-free device.
